Serial No. 484,146.

To all whom it mdf] concern.:

le it known that I, firicxaxonn E. Zinsen, a r-itizen ot' the United States ot' America, residing in the city of St. Louis and State souri, have invented certain new and uset'ul linprm'enients in Nut-Looks, of which the ,following is a full, clear, and exact description, reference being'had to the aecompanying drawings, forming part ot' this specification.

M v invention relates to nut locks, and it has for its object the production of a nut loch' by which a nut may be held from rotation upon a bolt or other screw threaded object and which permits of a nicety of :u'ljustment of the nut before the locking member is applied thereto in order that the nut may be held in the precise position to which it is desired to adjust and retain it.

Figure I is an end view of my nut lock. Fig. ,il is a side elevation of the nut lock. llig. III is a longitudinal section. Fig. IV is an end view ot' the nut used in my nut lock. Fig. V is a t'ace view of the nut locking ring'.

ln the accompanying drawings: l designates a screw threaded member, such for instance, as the shank ot a bolt or the stein oit an axle spindle and which is provided with a longitudinal groove 2.

3 designates a nut applied to the member 'l and which may be in the main of any desired configuration. This nut is provided at its outer end and externally thereof with studs 4L extending in a circular series, and located intermediate of the hole in the nut and the outer edge ot the nut. The studs t have beveled outer faces as seen in Fig. III.

t3 designates a split spring locking ring, preferably of steel7 that is applied to the nut 23 and eneircles the series ot studs upon the nut, the locking ring being beveled at its inner edge to provide for its engagement with the beveled outer faces of the studs 4 which extend inwardly toward the center of the nut and serve to prevent slippage of the locking ring from engagement with said studs. At one end of the split locking ring is a head 'T that is of sufficient dimensions lo extend from the outer edge of the ring to a point near the hole in the nut 3. The head ot the ring is provided with a central aperture S that is adapted to receive either' of the studs 4L on the nut when the locking ring is applied to the nut, and said head is of sutiioient width to cause its side edges to bear against the sides of two of the studs adjoining that which enters into the apen ture S in the head in order that the head will be firmly held between the studs at the sides thereof while it is itted to the stud that passes therethrough. At the inner end of the head of the locking ring is a tooth 9 that enters into the longitudinal groove in the shank of a bolt or other threaded member l when the locking ring is fitted to the studs of the nut, as explained.

It will be seen trom the foregoing that the nut 3 may be adjusted to any desired degree upon the threaded member and that when either of the studs upon the nut is brought into alinement with said groove, the locking 'ring may be applied to said studs to encircle them and with the head of the ring opposite the groove so that when said head is fitted to the stud that is opposite the groove and between the two studs adjoining the iirst stud at each side thereof, the locking ring will be held to the nut and the tooth 9 of its head having entered into the groove will act to restrain the nut from rotation upon the threaded member. The locking ring being of spring material and being beveled at its inner edge for engagement with the beveled outer races of the studs of the nut, is held in close itting engagement with said studs and there is, therefore, no liability of dislodgment of the locking ring from the studs.

I claim l. The combination with a threaded member provided with a longitudinal groove, of a nut having studs located externally thereof at its outer end, a split spring locking ring having a head at one end provided with an aperture receiving one of said studs and with a tooth entering into the groove in said threaded member, said head being of a width to permit ot its bearing against one of the next adjacent studs at each side of the stud extending through the head.

2. The combination with a threaded member provided with a longitudinal groove, of a at their outer faces, and Said ring being bev4h nut having studs located externally thereof eled :tt lts inner edge to engage the beveled at its outer end, a split Spring looking ring outer faces: of the studs.

having a head at one end provided With an l ALEXANDER- E. ZEESE. aperture receiving one of Said studs and with ln the presence of*w a tooth entering into the groove in said E. M. HARRINGTON,

threaded member, said studs being beveled E. B. LINN.
